Specification of Letters Patent.

Patented Feb. 11, 1908.

- Application filed December 5. 1905- Serial No. 290381.

To all whom it may concern: v Be'it known that I, WILLIAM B. PAL- MER,.a citizen of the United States, residi at Greenwich, county ofWashington, an State of-New York; have invented certain following is aspecification.

. he invention relates to such improvements and consists of the novelconstruction and combination of arts hereinafter described and subseuently claimed.

gReference may ehad to the accompanying drawings, and the referencecharacters marked thereon, which form-a part of'this specification. y

Similar characters refer to similar parts in elevation of my improveapparatus for inverting tubular fabric; Fig.- 2 is'a front endcross-section of the tubular support for the fabric taken on the brokenline 3-3 in Fig. 2. 'Fig 4 is across-section taken on the ofonebf thejfeed-ro ers. for drawing the fabric upon its tubular support. Fig. '5is a cross-section taken, on the broken line 55 in Fig.1 on a planepassing through the axes of the 006 crating feed-rollers and transverselof t 1e interposed tubular support for the fa ric.

fabric is commonly knitted in the form of a tube 'upon circularmachines, in'many cases e rough or unfinished side of the fabric"outermost. ln such cases, and in other cases where the subsequenttreatment of the fabric demands such a course, it is customary beforecutting the garment from 1s acco plished by drawing on'end of the webout through the other end preparatory theimetal tube one end of theweb,isinserted in the neighbori end of the tube and drawn therethroug andout fromthe other My invention relates more particularly to of fabric uon the tube preparatory to inversion ofeweb.

-.The principal objects of the invention are to faci itate thedepositing of the tube of l fabric upon the supporting tubepreparatoryto inversion and to prevent lllJllIY toth'e fabric while thusbeing placed upon the sup;

porting .tube.

Other ob ects of the invention will appear in connection with thefollowing descri tionn Referring to the drawings wherein t e inventionis shown in its preferred form, 1, represents a supporting tube adaptedto receive the fabric preparatory to inversion of the web, whichtube ismade in telescoping sec tions, the purpose of which will be herein-.

The outer section or end, 1%,;

after set forth. of'the supporting tube is interposed between a'pair offeed-rolls, 3, fixed u on the res Qr'} tive shafts, 4,, eaclrrotativeymounte in bearings in a vibratory frame, 5, hinged at,.6, to the floortimbers. nects together the upper vibratoryends of said bearing framestending to'draw the same-- A coil-spring, 7, con-' together so as toforce the feed-rolls, .3,

against opposite sides of the supporting tube,-

1, as indicated by dotted lines in Fig. 2.

Power is transmitted to the shafts, 4,

through pulleys, 8, fixed thereon respectively,

and connected by belts, 9, respectively with. the pulley or pulleys, 10,fixed upon a driveshaft, 11, one of said belts being crossed,

whereby rotative movements in op osite directions can be imparted toboth ro s, 3, in a-.

direction to engagje and force inwardlyalon' e, 1, a Web of fabric placethe supporting tu upon the latter.

To facilitate the application of the fabric to the su porting tube andits removal there. from, provide a brace, 12, in the form of a toggle, tc outer ends of which are hinged to the respective bearing frames, 5,said toggle when fully opened serving to braceand hold said frames apartwith the rolls, 3, withdrawn from the supporting tube, 1, in whichposition said togg e is adapted to be automatically locked by aspring-catch, 13, which may be of any known form adapted to be releasedby the hand of the operal or when it is desired to close the toggle topermit the spring, 7, to draw the bearing frames together,

The feed-rolls, 3, are preferably formed with a concaved erlph sry, 14,across the hollow-orgroove 0mm! by which are secured strips. 15', ofleather or oth r flexible.

.m'aterial-adapted to bear upon the engaged fabric with sufiicient fri.;tion to properly feed the same but Without injury thereto Intheoperation of the a paratus the feedrolls, 3, are'held removed ingtube,1, while the end of the tubular web pr fabric, 16, drawn from a basketor box, 17, 1s shpped over the end of the outer section of thesupporting 12, is operate and permit the feed-rolls, 3, to be forcedinto engagement with the fabric on o posite sides of the supportingtube. As the eed-rolls are rotated, successive ortions of the tubularweb of fabric arepus ed by the feedrolls in- I wardly alon thesupporting tube until the as been. thus applied thereto,.

gvflzple web 1' which -the feed rolls are again withdrawn from thesupporting tube permitting I the unobstructed removal of'thefabricfromthe feed-rolls 3. The feed-rolls, 3, are fixed upon the sameshafts, 4, as the respective feed-rolls 3'. 3 1 The object of making thetube, 1, in telescop' sections is to permit the. end section,

l: 1 to be slid inwardly alon the body section I enga e of .the'tube towithdraw it mm between the feed-rolls, 3,: to permit said rolls to bebrought into closer proximity to -each other {when it is desired to havethe iced-rolls, 3 the upper tube 1". By employing a pl ity of suchsupportin (tubes with feed mechanism cooperative wit each separately Iam able to carrfy on the-operation of ap lyabric to one of said tu es,

' w e another web of fabric previously apwhen not in use.

plied to the other of said tubes is being 1nverted.

- The upper roll, 1*, is pivotally mounted at, 18, upon a suitablesupport whereby it is adapted to be swung upwardly out of the way Anautomatic s ring-catch, 20, serves to prevent inward te escopicmovements of the end section, l'g of the tube, 1, during .the 0perationof the feed-rolls,3,fin engagement therewith.

What I claim as new and desire to secure by Letters Patent is 1. In anapparatus of the class described, the combination with the fabric suporting tube; of a pair of feed rolls ada cc to? en-v g e the opposite.sides of sai tube; and yie ding means for j forcing said feed-rollsagainst said tube. I
